Bilateral agreements and arrangements allow the airworthiness certification of civil aeronautical products to be shared between two countries.
A Bilateral Aviation Safety Agreement (BASA), Memorandum of Understanding (MoU) or Working Arrangement (WA) and their associated implementing procedures provide for technical cooperation between national civil aviation authorities. They help reduce duplication of activity and aim for mutual acceptance of certificates.
In addition to airworthiness certification, BASAs, MoUs and WAs provide for bilateral cooperation across other areas of aviation, including maintenance, flight operations, and environmental certification.
For aircraft certification and maintenance, additional implementation procedures will cover specific issues such as design approval, production acceptance, export airworthiness approval, post-design approval activities, technical cooperation and maintenance.
UK component acceptability table
In order to properly control the acceptance of components being fitted to UK registered/operated Aircraft, Engines or components which fall under the control of UK and partner countries BASA’s or working arrangements these tables provide an overview of what is required in terms of documentation to allow fitment. This is provided as reference only, you should always refer to the latest version of the bilateral agreement or working arrangement on this page to gain the latest information.

Notes
- An EASA Form 1 released by a UK based EASA Part 145 organisation is not acceptable for installation on a UK registered aircraft or component for fit onto a UK registered aircraft.
- For an EASA Form 1 from an EU based EASA Part 145 organisation dated after 31st Marc 2022 to continue to be acceptable, the organisation issuing the EASA Form 1 must have applied for a UK Part 145 approval before that date.
- An EASA Form 1 from a UK based EASA Part 145 TCO organisation is not eligible for installation on a UK registered aircraft as stipulated in ORS 1516.
- In accordance with the UK/Canada working arrangement, components up to and including complete engines and propellers are considered mutually acceptable, therefore can be accepted on a TCCA Form ONE from a Canadian based AMO.
- In accordance with the UK/Brazil agreement, components except for complete engines and propellers are considered mutually acceptable and can therefore be accepted on an ANAC Form F-100-01. (formerly SEGVOO 003), from a Brazilian based AMO.
- In accordance with the UK/Singapore arrangement, components excluding complete engines, APUs and propellers, are considered mutually acceptable and can therefore be accepted on a Form CAAS(AW)95 from a Singapore based AMO.
- In accordance with the UK/Singapore arrangement, complete engines, APUs and propellers, are considered mutually acceptable when repaired by a Singapore based AMO, released on a CAAS(AW)95 and the Singapore based AMO has an approved UK supplement.
- For an EASA Form 1 to be issued/accepted from a Japan/Singapore based organisation then they must of held an EASA Part 145 or 21G organisation approval prior to 31 December 2020
European Union
The trade and cooperation agreement between the EU and the UK addresses aviation safety at Article AIRTRN.18.
The UK Civil Aviation Authority (CAA) and EASA have concluded negotiations on the Technical Implementation Procedures (the TIP), which was signed at a ceremony on 17 May 2021.
Approvals covering design and production of civil aeronautical products
UK-EU Airworthiness and Environment Certification: Draft Design Certification
Existing design certificates status
The UK-EU Trade and Cooperation Agreement recognises:
- Type certificates,
- supplemental type certificates,
- approvals for changes and repairs, and
- technical standard order authorisations
issued by EASA or an EASA approved design organisation that were valid on 31 December 2020.
These are considered to be accepted by EASA and CAA in accordance with ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 15.
Design changes
The UK-EU Trade and Cooperation Agreement states that minor changes and minor repairs approved by CAA or a CAA approved design organisation are accepted by EASA and vice versa.
Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 13
EASA approved design changes
The UK-EU Trade and Cooperation Agreement states that non-significant supplemental type certificates, non-significant major changes, repairs and technical standard order authorisations issued by EASA or an EASA approved design organisation will be accepted by CAA. Further clarification on classification will be provided in the CAA/EASA TIP.
Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 13.
CAA approved design changes
The UK-EU Trade and Cooperation Agreement states that type certificates, supplemental type certificates, approvals for major changes, major repairs and technical standard order authorisations issued by CAA or by a CAA approved design organisation will not be directly accepted by EASA and will be subject to technical validation by EASA. In some cases, when agreed by CAA and EASA, a streamlined validation may be performed.
Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 10.
Technical validation of EASA approved design changes
The UK-EU Trade and Cooperation Agreement states that type certificates, significant supplemental type certificates and approvals for significant major changes will be subject to either technical validation or streamlined validation by CAA. Further clarification on classification and corresponding validation path will be provided in the CAA/EASA TIP.
Further details can be found in ANNEX AVSAF-1 AIRWORTHINESS AND ENVIRONMENT CERTIFICATION, Article 10.
UK-EU Airworthiness and Environment Certification: Production
EASA POA (as Third Country Approval) for UK goods to be accepted in the EU
The UK-EU Trade and Cooperation Agreement enables the EU to recognise the POA issued by the UK CAA for categories of products that are already approved for production on 31 December 2020.
UK POA for EU goods to be accepted in the UK
The UK-EU Trade and Cooperation Agreement enables the UK to recognise the POA issued by the EASA CAA for categories of products that are already approved for production on 31 December 2020.
Export to the EU
The UK-EU Trade and Cooperation Agreement recognises the CAA Form-1 for the export of new parts, appliances, engines and propellers and CAA Form 52 for the export of new complete aircraft.
Therefore, there is no need for UK-based organisations to hold an EASA Third Country Production Organisation Approval. Consequently, EASA has not issued any Third Country POA to organisations in the UK and as such, there are no EASA.UK.21G.XXXX approvals.
Export to the UK
In the UK-EU Trade and Cooperation Agreement the UK recognises the EASA Form 1 for the export of new parts, appliances, engines and propellers and EASA Form 52 for the export of new complete aircraft.
Therefore, there is no need for an EU based organisation to hold a UK Production Organisation Approval.
